Sourcing Vape Coil: ISO factory audit walkthrough
This page is for first-time buyers who want a working answer on specification, price and lead time before they commit a purchase order. We have written the detail down so nobody has to sit through a sales call to extract it.

What happens when something goes wrong
We work with first-time buyers who order between a few hundred and a few thousand units at a time, and we treat both ends the same way: a written specification, a sample you approve, and a production run that matches the sample.
Reorders are the real test of a supplier. If the second shipment does not match the first, the relationship is over regardless of price, so we treat the reorder as the actual deliverable.
Returns are handled as data, not as complaints. Every reported failure is logged by mode and by batch, and the pattern is reviewed monthly with the factory.
Unit price versus landed cost
Currency moves more than most buyers expect over a twelve month supply plan. We quote in USD and hold the price for 30 days from confirmation so your margin calculation is not guesswork.
Payment terms for new accounts are normally a deposit with the balance against the bill of lading. Established buyers on a repeat schedule can move to terms after three clean shipments.
Shipping without surprises
Damage in transit is nearly always a packing decision, not bad luck. Double-walled cartons, internal dividers and a drop-tested configuration cost a little more and save the argument at the other end.
Freight on vape coils is driven by volume more than weight. Cartons are designed to hit a clean pallet count, which is why a slightly denser pack can cut your landed cost by more than a discount on the unit price ever would.
- Cartons drop-tested and pallet-counted for clean freight
- Artwork proof plus physical dummy for custom packaging
- Consolidated or split shipping, quoted both ways
- Specification locked in writing before production starts
- Mixed SKU cartons to spread first-order risk
- Batch codes traceable from carton back to production date
Where defects actually come from
Flavour drift between batches is the quiet killer of repeat orders. We retain a sealed reference sample from every run so a complaint six weeks later can be compared against what actually left the building.
Battery safety is not a marketing line. Cells are matched by capacity and internal resistance before assembly, charging boards are checked for cut-off voltage, and any unit that fails the cut-off test never reaches packing.
Specification summary
| Resistance | 0.40 ohm |
| Build | Clapton |
| Wicking | Cotton bacon |
| Fitment | Magnetic |
| Pack size | 3 per pack |
| Compatibility | Universal deck |
| Minimum order | 300 units per SKU, mixed cartons allowed |
| Lead time | 30 working days after artwork approval |
None of this is complicated. It is just written down, which is more than most buyers get before they wire a deposit.
Frequently asked
Can you ship to multiple locations?
Yes. Split shipments are quoted separately because consolidation and splitting price differently. Tell us the destination list at quotation stage and we will show both options.
What documents come with a shipment?
Commercial invoice, packing list, and the certificate pack for your market: test reports, declaration of conformity and safety data sheets. We send scans before dispatch so your broker can pre-clear the file.
How long does production take?
Around 15 working days after artwork approval for stock configurations, plus transit. Custom runs add roughly a week for tooling and a physical dummy. We confirm the date in writing on the order acknowledgement.
